A high-ranking police official told CNN that the explosion appeared to be the result of a suicide attack.
The perpetrator, identified as José Aldemar Rojas Rodríguez, also died in the attack, police said in a statement.
    Attorney General Nestor Humberto Martinez said Rojas Rodriguez allegedly had approximately 80 kilograms of explosives when he entered the police academy forcibly. Rojas Rodríguez rammed a vehicle onto the grounds of the academy at full speed and ignored calls to stop, according to police.

    He also proclaimed a three-day period of mourning.
    "From the moment of the events we have provided assistance and accompaniment to families. To all of them I send my love, my gratitude," he said.
